Answer:

In evolutionary biology, abiogenesis, or informally the origin of life (OoL), is the natural process ... For the oldest life forms, see Earliest known life forms. ... There are several principles and hypotheses for how abiogenesis could have occurred. ... In 2017 scientists found possible evidence of early life on land in 3.48 Gyo

Explanation:

Many scientists favor the RNA world hypothesis, in which RNA, not DNA, was the first genetic molecule of life on Earth. Other ideas include the pre-RNA world hypothesis and the metabolism-first hypothesis. Organic compounds could have been delivered to early Earth by meteorites and other celestial objects. We can only speculate about these questions, since we haven't yet found any life forms that hail from off of Earth. But we can think in a more informed way about whether life might exist on other ... When did life appear on Earth? ... For many millions of years, early Earth was pummeled by asteroids and other celestial objects.

The neandertal site in croatia that has produced hominin remains showing the full suite of classic neandertal morphology is:____
AlekseyPX

The neandertal site in Croatia that has produced hominin remains to show the full suite of classic Neandertal morphology is Krapina.

Explain the morphology of Neandertal.

Below 55 degrees North latitude, Neandertals inhabited Western Eurasia. Notably, none have been identified in North Africa despite their presence south of Haifa (Israel), despite their presence.

Paleogenetic evidence suggests they existed in the East, reaching as far as Southern Siberia. This distribution depicts the northern boundary of the eco-geographical range of humans in the Late MP and Early LP.

This had significant ramifications for the Neandertals' biological adaptations, the pattern of terrain occupation, and demography. They were large-bodied hominins with higher energy needs than the majority of modern hunters and gatherers.

All of the isotopic studies that are currently available indicate that their primary source of protein was animal, and the archaeological record paints a picture of effective hunters who concentrated on medium-sized prey.

Hence, the answer is Krapina.
